Neuma 4 Modus Tattoo Pen - Midnight - 33mm Grip
Order number: NE4-MO-DBU-33-4.2MM>>> Neuma Information Package <<<
Please note: For the operation of Neuma machines, a power supply with high amperage (5A+) is advisable. We recommend a power supply from Musotoku for this purpose.
Important note!
To guarantee the longevity of the machine, the maintenance prescribed by the manufacturer is absolutely essential! Oil the cams approx. every 100 hours of operation + when changing the cams.
Fill the enclosed oil into the underside of the cam (until 1 drop spills over)
Cam and motor pin are now oiled to ensure the necessary lubrication
The game changer: Neuma 4!
The Neuma 4 is a tattoo pen with a rotary drive and a newly developed transmission, which makes the pen feel like a coil machine while working and also has a similar effect on the skin.
At the same time, you retain all the advantages of a rotary pen, such as reliability, easy configurability, low maintenance and high ergonomics.
Due to the coil machine-like behaviour, the needle pierces straight into the skin, causing far less trauma and achieving cleaner results.
The highlight: the Cams
A cam is what changes the so-called dwell time of the needle, that is, the moment the needle will jab in and out of the skin.
What this means is: how quickly does the needle move into and out of the skin, how long in total does the needle stay in the skin during this process and why is this important in the first place?
Lining - Shading - Blending - Colour Packing
Each tattooing style has different requirements. Which machine with which features do you use for which style?
The stroke determines how fast, short=hard or slow=soft, the needle hits the skin and how fast it retracts. In relation to the cycle of a complete needle movement - i.e. 1 x there and 1x back again - time span = 100%, the needle therefore dwells in/under the skin for different lengths of time (dwell time).
In general, the lower the percentage, the faster the hand movement can be. Higher percentages are better suited for slower hand movements.
That is why Neuma has developed four different "cams". Each cam changes the dwell time in a different way and is adapted to the respective tattooing technique. The cams allow you to tattoo any tattoo style with one machine by changing the speed and the way the needle penetrates and stays in the skin.
And since each machine comes with 4 cams, you only need one machine: The Neuma 4 Tattoo Pen.
- the 20% Cam: Ideal for straight and clean lines - quick in, quick out.
This cam is inserted in your Neuma 4 Tattoo Pen on delivery. - the 28% Cam is suitable for fast shading - a little slower in, but as fast out as the 20% Cam.
- the 33% Cam is perfect for smooth transitions for gradients with several layers and slower shading - a little slower in, but out as fast as the 20% Cam
- The 40% cam is the right choice for slow hand movements or for colour packing on large areas – as slow as the 33% Cam in and very slow out.
- Changing a cam is very easy: the pen can be opened with a twist. Then you can simply remove the cam inside and replace it with another one.
Cams also determine the stroke length. This means you can choose between 2.7, 3.5 or 4.2 mm stroke and order additional cams accordingly. There are 4 cams for each for this. You can order them individually or as a set. Our machines are equipped with the 4.2mm version as standard.
The needle protrusion can be continuously adjusted by a knob on the top of the Neuma 4 Tattoo Pen.
In addition, you can change the hit by replacing the bearing arm. The heavier the bearing arm, the harder the hit. A 5g brass bearing arm is pre-installed.
For a softer hit, there is a separately available 1g aluminium bearing arm. Here, too, the exchange is relatively easy - a fitting Allen key is of course also included.
Overall, the Neuma 4 Tattoo Pen is one of the most configurable tattoo machines in the world.
What exactly makes the difference?
The fundamental difference between coil and rotary machines is, of course, first and foremost the type of drive.
The developers at Neuma have taken a closer look at the differences and found that they relate specifically to the action and behaviour of the needles. These differences affect both your working behaviour and feel, as well as the interaction with the client's skin.
How the needle penetrates the skin and how long does it stay there, and why this is more important than you think.
With coil machines, the drive is direct or linear. I.e. electromagnetic pulses move the springs of the coil machine and thus the needle bar/needle up and down in a very straight line. The needle pokes in the skin quickly and comes back quickly - it "sticks" because it "only" moves in two directions.
With rotary machines, the needles first spring back against the resistance of the skin due to the rotating movement and only then penetrate the skin. The rotary motion also transfers to the needle, causing it to "dig" more into the skin than piercing it, which can lead to additional trauma to the skin tissue. This effect is not quite as pronounced with rotary pens. However that does not change anything regarding the dwell time.
Looking more closely at the dwell time, it is noticeable that the length of time the needle stays in the skin varies greatly between the different types of drive: with conventional rotary machines, the needle dwells in the skin for up to 40% of this time, compared to about 10-15% with a coil machine.
The longer dwell time and the "scooping" of the needles can lead to "snagging", which traumatises the tissue more. Then you have to change your approach, e.g. to achieve good lines or a desired effect.

What are the differences between the stroke profiles (Cams)?
Each of the stroke profiles will give a different result. The percentage used to describe them is related to the amount of their cycle the needles are spent in the skin (extended). The smaller the percentage, the faster the needles are extended and retracted, which allows for faster hand movement across the skin.
These are our generally recommended uses for each of the cams:
- 20% – Liner and/or fast hand movements
- 28% – Faster Shader or color blender
- 33% – Multi-pass blender or slower shader/color-blender
- 40% – Packer or very slow shader/blender
What is the best stroke profile for me?
Different people have varied results from the different cams and tend to have their own preferences. For this reason, Neuma includes all 4 stroke profiles with every new machine purchased. This way, each artist can experiment to determine which cam is best for them. Neuma sets up all new machines with the 20% cam, and recommend all artists try this one first. Neuma feels it is best to get accustomed to each cam before experimenting with the next one for best results. When it comes to stroke length, this is simply a matter of preference with this machine.
Do cams adjust stroke length or stroke profile?
Cams adjust both stroke length as well as stroke profile. Cams come in sets of 4 for each stroke length. That means there are a total of 12 cams, 4 for each stroke length. Generally, an artist will choose a preferred stroke length, and then they can switch between the 4 different cams to change stroke profiles as needed. Cams are swapped without the need for any tools.
Some artists prefer to have more than one machine (each machine having a different stroke profile) to avoid the need for swapping, but it is only a matter of convenience since the switch takes only a few seconds.
How do I adjust needle throw/ depth?
The End Cap, which is the smaller “knob” towards the top of the machine (opposite side of the cartridge) can be turned against the grip to achieve a different throw. This is different from stroke length. Stroke length determines the maximum amount of needle throw available, as well as the speed of a cycle with a given voltage applied. In contrast, the throw is the amount of stroke that is being used, or the exposure of the needle beyond the end of the tube tip when it is in its extended position.
What is the purpose of the heavy-duty spring?
The heavy-duty spring, in most cases, is not necessary. The circumstances which will potentially require the use of a heavy-duty spring are:
- An artist who operates their machine at very high speeds
- An artist who uses a very short throw/ stroke
What parts might I need to replace and how often?
Regular wear parts are designed to last a long time, but will occasionally require replacement, depending on how a given artist uses the machine. The harder a machine is run, the faster these parts will wear out. Also, when a machine is properly oiled (every 50-100 hours of operation, 1 drop into the cams center hole) it will have a longer lifespan. Wear parts include Cams, Bearing Arms, Springs, RCAs, and Motors. NOTE: Motors will last a very long time when cared for but are expensive to replace. If a machine is dropped it can cause immediate irreparable damage to a motor. Also- do not apply any pressure to the motor shaft in any direction (the center post that the cam slides onto).
What is the difference between the 2 Bearing Arms?
Our two Bearing Arm options are a 1-gram Aluminum Bearing Arm and a 5-gram Brass Bearing Arm. The heavier the Bearing Arm, the harder the hit. Neuma recommends the Brass Bearing Arm for everyone, but if you prefer the lightest possible hit, then you might prefer the aluminum one. All machines come standard with the Brass bearing Arm.
How often should I oil my machine?
Oiling is an important part of Neuma maintenance, and it should be done every 50-100 hours of operation. Neuma recommends using only the provided oil and cleaning out the inner cavity and cam each time you oil as well. Be careful not to put any pressure on the center motor shaft or bend the side Anti-Rotation Pin while cleaning. Also, be aware that if you are regularly switching between cams that each of the cams need to be oiled separately.
How do I oil my machine?
Remove the cam to be oiled, flip it over so that you are looking at the hole in the back of it where the motor shaft inserts into, and drop one drop of oil into that hole. Then replace the cam onto the motor shaft, being careful not to apply any pressure to the shaft.
What needs to be done to keep my machine operating efficiently?
To keep your machine operating strong and efficiently, here are a few things to do:
- Oil regularly (every 50-100 hours of operation or between cam switches if not previously oiled)
- Clean the inner cavity regularly (every time oiled, or 50-100 hours) with a Q-tip. Occasionally, you can remove the bearing arm with the provided alan key and do a thorough cleaning by wetting a Q-tip with alcohol, being careful not to allow alcohol to get into the center hole/motor chamber.
- Visually check the side Anti-Rotation Pin to be sure it is still straight up and against the side wall of the cam chamber. Be careful not to bend this when cleaning.
- Keep spring stretched to a length of 2 inches for proper tension. They can eventually become a bit shorter but can easily be stretched back to length.
Why is my machine’s oil turning dark gray?
This is a normal process that happens to oil, and nothing to become concerned about. It is due to a process called lipid peroxidation, and it is unavoidable. Neuma recommends using a Q-tip occasionally to wipe away old oil and re-oil your cams.
What should I expect when converting from coil machines to Neuma 4?
You will not notice a significant change when switching from coils regarding needle-action. Mostly, you will notice the change in weight distribution, ergonomics, and a reduction in maintenance and no need for tuning.
What should I expect when converting from traditional rotary machines to Neuma 4?
Neuma Tattoo Machines will feel quite different from traditional rotary-style tattoo machines, both in the weight distribution and balance, as well as the way the machine tattoos and the feel of the hit. They will feel very “snappy”, a big improvement in lining ability and speed, and usually they will increase your efficiency and speed at which you get your work done. Neuma machines do make more sound than traditional rotary machines, which can be very useful as a form of audible feedback. They sound like a much quieter version of a coil machine.
Can Neuma machines be cold-sterilized?
Yes, it is safe to cold-sterilize all Neuma grips by soaking them with madacide, wavacide, cavacide, or similar. Do not use bleach. It is harmful to Neuma components and not a sufficient sanitizer. Also, do not submerge motor assemblies as this will cause irreparable damage to the motor inside and require replacement. Motors are not covered by warranty because Neuma cannot guarantee they are properly cared for, but they can be replaced without the need for buying a new machine or motor assembly.
Can the spring be left in the grip for sterilization?
The spring can be left on the grip for sterilization but will corrode faster than the other materials and will eventually need replacement. Also, springs are not covered under warranty as they are wear parts.
